Season 8: Episode 171: The One With The Red Sweater

As they prepare to leave the wedding hotel, an excited Monica and Phoebe speculate about who might be the father of pregnant Rachel's baby while the expectant mother debates whether she should tell the unsuspecting dad at all. At the same time, Joey mistakenly thinks Phoebe is preggers -- and makes a gallant gesture -- while Ross and Chandler frantically try to re-stage generic wedding photos with other couples at the hotel when Chandler loses the film from his own ceremony. Meanwhile, Monica can't wait to tear into her tantalizing wedding gifts.
